I have a PHP script that I purchased from Code Canyon and after installing the script and linking the payment gateway to PayPal, an error appeared on my site during the payment experience The problem is that when I click on the Pay Now button for Paypal, the page is refreshed again and the Pay Now button appears again, and every time I click on Pay Now, my Paypal account is debited, but my money is returned automatically after a short period, The problem is that there is an iterative loop and the payment page is refreshed without redirecting to my site again
